What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Bremont S300

Owners widely praise the Bremont S300 for its comfortable 40mm size, fitting well under a cuff, and its appealing dial and bezel color. The winding action is described as smooth, and timekeeping averages +3 seconds per day, with machining noted as being on par with higher-end brands. One owner suggests tapering the bracelet and adding a mixed brushing and polishing finish for improved dress-shirt wearability. However, some find its styling lacks uniqueness compared to competitors, and the approximately 49mm lug-to-lug measurement is considered unusually long and potentially ill-fitting on smaller wrists. Overall, owners rate the Bremont S300 highly for its wearability and finishing at its price point.

CWC E9 Quartz Diver Watch

The CWC E9 Quartz Diver Watch is praised for its historical significance, unique Jolly Roger dial, and military-spec build. Owners report it is thin, small, very legible, and has a satisfyingly easy-to-wind crown, with some noting its accuracy and clean lume application. However, the luminous paint on the Jolly Roger is described as low glow, and one owner reported their T20 model had an inaccurate quartz movement and a soft acrylic crystal that scratches easily. Some find the Jolly Roger design "out there," while others like its unique aesthetic. Some feel it is overpriced for its components, particularly the standard Ronda movement. Overall, owners rate the CWC E9 Quartz Diver Watch highly for its unique aesthetic and military-inspired build.
